The Sandy Bridge Preview (Anand)

[ajaidev]

I still have my doubts about the 480SP part (not that there is going to be such a SKU)... that thing will be so bandwidth starved, it will be ugly. Sure it will beat every other igp out there, but there will be so much performance given away...

A 5670 has 68 GB/s... Llano at best can offer 25.8 GB/s, maybe 34 GB/s if they support DDR3-2133. Half of what a 5670 offers, and it has 80SP less.

5570 offers 28.8 GB/s and has 400SP's. While it is not as powerful as the 5670 "Other stuff has also been taken out" its not a performance disaster due to low bandwidth. Also the 5570 works on 650mhz core and 1.8Ghz memory.

Looks like Llano is going to have a tough job keeping up with mid-range Sandy Bridge(4c non HT/2c w/HT) on the cpu side.

Yep but that was expected and has not changed ever since it was known that llano is based on K10.5 aka stars cpu.
